Samsung Galaxy S23 Ultra is an unbeatable camera smartphone, thanks ISOCELL HP2
Samsung continues to innovate camera and sensor technologies to provide a professional-level camera experience on smartphones. The Samsung Galaxy S23 Ultra boasts a professional-level camera with the ISOCELL HP2, the largest sensor of the Galaxy series with adaptive pixels, and diverse advanced technologies.
The ISOCELL HP2 is the largest image sensor in the Galaxy series ever, featuring a 200-megapixel resolution. With massive resolution integrated, the sharpness of colors and images is increased, and even the smallest details of the moment can be recorded even in difficult environments.
From 200-megapixel that delicately record everyday moments, to AI-based advanced pixel technology for Nightography, fast and accurate autofocus, and 8K video shooting with a wider angle of view. Let’s enjoy the special camera experience provided by the Samsung Galaxy S23 Ultra with the ISOCELL HP2.
High-resolution image capturing
A 200-megapixel image is 16 times larger than a 12.5-megapixel image. In other words, it contains 16 times more information and details. In general, cropping or enlarging an image reduces the number of pixels, resulting in a blurry picture, whereas a high-pixel image can maintain a relatively high resolution even after cropping.
In the case of a 200-megapixel image taken with the Galaxy S23 Ultra, even if it is cut in half both horizontally and vertically, there are still 50-megapixel left to preserve the richness and clarity of detail. In addition, ISOCELL HP2 implements the color of images more accurately through advanced deep-learning algorithms.
New pixel structure
Samsung improved the pixel structure so that each pixel in the ISOCELL HP2 image sensor can absorb more light and express richer colors. The newly designed pixel structure, Dual Vertical Transfer Gate (D-VTG), enables accurate color expression even in an overly bright environment.
Three ways in one package
- 200-megapixel, 50-megapixel and 12-megapixel
The Galaxy S23 Ultra’s ISOCELL HP2 camera allows users to shoot with the optimal pixel they want through adaptive pixel technology. Tetra2pixel technology utilizes all 200 million pixels when taking pictures, or uses them in groups of 4 or 16.
In basic mode or in a dark environment, 12-megapixel shooting that captures a lot of light with large pixels provides bright and clear pictures, and in bright environments that require detailed description, all 200 million pixels are used to capture rich details in images.
Striking NIGHTOGRAPHY
Samsung Galaxy S23 Ultra’s Nightography feature has dramatically improved the shooting experience in dark environments. Powered by AI image signal processing technology, the data stored in the image sensor provides clear color and quality as if you were seeing it with your eyes even at night.
Here, the tetra-squared pixel technology of ISOCELL HP2 merges 16 adjacent pixels into one in a dark environment and adjusts the size to 2.4um so that one pixel absorbs more light. This absorbed light information is optimized with the Galaxy S23 Ultra’s advanced AI technology and reborn as a bright and clear picture.
Speed and accuracy
The ISOCELL HP2 improves autofocus technology and enables sharp capture of fast-moving subjects. Unlike previous products, Super QPD autofocus technology is characterized by utilizing all pixels of the image sensor for phase difference detection.
Super QPD technology, which uses all 200 million pixels for autofocus, can quickly and accurately capture moving objects, compared to 180 million pixel products that use only 3% of the pixels of the image sensor for phase detection.
8K videography at 30fps
For 8K video shooting, the ISOCELL HP2 uses tetra-squared pixel technology to combine four pixels into one large pixel to operate as 50 million pixels. Users can shoot cinematic 8K videos at 30fps with brighter, clearer colors and a wider angle of view.

Including Samsung, global IT and semiconductor companies such as Google, Intel, Nvidia, and Qualcomm are participating. Companies participating in the RISE project, including Samsung, plan to jointly develop software based on RISC-V.
“We will participate in the RISE project and collaborate with other companies to build a sustainable RISC-V-based open source software ecosystem,” said Park Soo-hong, head of the Open Source Group at Samsung Research and a member of the Linux Foundation board of directors.
It is easy to implement applications or services, which operate on RISC-V-based chipsets, and resources required for development and maintenance can be reduced. It’s expected to be used in various fields such as mobile, home appliances, data centers, and vehicle applications.
Meanwhile, RISE operating board members include Samsung Electronics, Google, Intel, Nvidia, Qualcomm, Red Hat, Mediatek, Andes, and Imae Thirteen companies including Imagination Rivos, SiFive, Ventana, T-Head are Samsung participating.

Let’s take a look at how Samsung Biometric Card IC can make card transactions PIN free and convenient, solving one of the world’s most pressing payment and identification problems. The video mentioned below gives you a high-level understanding of how it will change the way people pay in the future.
What the video below:
Samsung Biometric Card IC
An innovative payment card technology called a biometric card offers cardholders a secure and convenient way to authenticate themselves at the point of sale (POS) by using their fingerprint instead of a personal identification number (PIN) or signature.
Cardholders don’t need to enter a PIN for high-value transactions, making transactions faster and easier. An added layer of security reduces concerns about the card or PIN theft and increases confidence in using the card, especially when traveling because you don’t have to worry about fraudulent payments even if your card is stolen or lost.
Samsung’s latest Galaxy S23 series brings some of the best camera smartphones out there. Following the launch, it was noticed that the non-Ultra models of Samsung Galaxy S23 have some issues, causing blurry close-up shots, which are now officially acknowledged.
What’s the issue?
Some Galaxy S23 and Galaxy S23 Plus smartphone users noticed that the area around the subject looks a bit blurred when taking a close-up shot. The impact of this problem is limited to both low-end models of the lineup, while the Ultra remains issue-free.
What’s the reason?
Samsung disclosed through its community post that Galaxy S23 and S23 Plus use a 50-megapixel primary camera powered by AI features and machine learning. The blurry close-up problem causes due to the sensor’s bright aperture, which makes stunning Nitghtography possible.
Fix coming in the future!
Samsung not only explained the issue and shared the reason, but also confirmed that the blurry close-up shots problem on Galaxy S23 and S23 Plus is planned to improve (fix) in a future software update. However, when this software update will release, remains a question for now.
Workarounds
If you are experiencing this on your Samsung Galaxy S23 or S23+, there are a few solutions you can try:
- Try taking a picture from a bit further away; if the subject you are photographing is about 30 cm away, move back a hand’s width
- Try to take a photo holding the phone vertically; if you hold the phone horizontally or diagonally, the background may appear blurred.
Why S23 Ultra is unimpacted?
Galaxy S23 Ultra remains unimpacted from the blurry shot issue as its camera automatically switches to the wide-angle camera and activates the focus booster to prevent blur. But do note that the focus enhancer stops working in high-resolution image mode, possibly resulting in a blurry close-up.
